Should I start Ray Rice vsPIT or Mike Tolbert vsOAK?

Fred Jackson is worth picking up rather you play him this week or not. Tolbert is running against the Raiders this week. Only the Lions, Broncos, and Cardinals have allowed more fantasy points to RBs. I would be playing him this week. Only one team has allowed fewer fantasy points to RBs than the Steelers and that's the Jets. This is not a good week to be playing either Green-Ellis or Rice. Jackson has a hamstring problem. Jackson's opponent, the Vikings, are allowing the 6th least fantasy points to RBs. The Steelers have allowed a lot more receiving yds to WRs than the Bills, but the Bills have allowed 5 more WR TDs. I'd play Harvin at home, but the choice between him and Welker is close.
